A couple of questions (because I'm new to FreeBSD): The ipfw man page in 5.2.1-RELEASE says that ipfw in CURRENT is ipfw2 and that ipfw in STABLE is ipfw1. I still don't understand the releationship between RELEASE and the other two, so I am not sure which ipfw I have in 5.2.1-RELEASE. I have read the following 5 excellent articles on ipfw, by Dru Lavigne. Even though they were written in 2001, and thus pre-date ipfw2, I found them to be a great crash course in ipfw, and the ipfw manpage in 5.2.1-RELEASE just adds to it. In Dru's first article, she(?) discusses how the kernel must be modified to support a firewall. She looks into /usr/src/sys/i386/conf/LINT to find the relevant information that needs to be added to my kernel conf file. I cannot find a LINT file on my 5.2.1-RELEASE system. Where can I find complete information on what I need to do to my kernel? TIA -ste P.S.: I find that ipfw rules are far more human-readable than I thought, and when comparing my linux server's ipchains rules to /etc/rc.firewall's "simple" firewall rules, I found them to be very similar. :)
